In this letter, a dual-band Multiple Input Multiple Output (MIMO) antenna system with high isolation is presented. This design consists of two dual-band monopole antennas and neutralizing transmission line. For each antenna element, the operating frequency band covers from 2.4GHz to 2.6GHz and 5.2GHz to 6GHz. To improve the isolation between these two antenna elements spacing only 0.1225λ0 at 2...

A novel dual-band design of a finite ground coplanar waveguide (CPW)-fed monopole antenna is presented for simultaneously satisfying wireless local area network (WLAN) and worldwide interoperability for Microwave Access (WiMAX) applications. The proposed antenna, comprising a rectangular planar patch element embedded with two L shaped slots and stair shape slot in the middle of the patch elemen...

In this study, we suggest and experimentally validate a methodology for fast and optimized design of dual-band implantable antennas for medical telemetry (MICS, 402–405 MHz, and ISM, 2400–2480MHz). The methodology aims to adjust the design of a parametric dual-band antenna model towards optimally satisfying the requirements imposed by the antenna-fabrication procedure and medical application in...

This paper describes a novel dual-band patch antenna on organic magnetic substrate for wireless local area networks (WLAN) wireless communication (at 2.4 and 5 GHz). The dual-band operation is obtained by embedding a pair of L-shaped slots. The magnetic material is adopted because the substrate can reduce the size of antenna 40%, comparing with rectangular microstrip antennas on normal dielectr...

1. Abstract In this design, the dual band dipole antenna feed network with wide bandwidth tapered microstrip balun is studied. The design and experimental results of low profile embedded microstrip dipole antenna with tapered microstrip balun shows fairly good performances. The feed network of the design with wider bandwidth and lower power loss tapered microstrip line to overlap coplanar strip...

In this paper, a design of CELL band dual polarized base station antenna having air dielectric substrates has been proposed. The study of dual polarized base station antenna and their radiation properties including return loss, isolation, beam width, directivity, and radiation patterns for a single element are discussed. The antenna has a relative bandwidth of 31.7% (VSWR<1.4) with return loss ...

A novel design of Dual band pyramidal serrated microstrip patch antenna was designed and Simulational results are presented in this paper. Equal spaced serrated pyramidal shapes are etched on four sides of the patch and its performance characteristics are simulated using commercial software HFSS. The current model is resonating at dual band with moderate gain. Return loss, radiation patterns, i...

This paper presents the design of a dual band rectangular Dielectric Resonator Antenna (DRA) coupled to narrow slot aperture that is fed by microstrip line. The fundamental TE111 mode and higher-order TE113 mode are excited with their resonant frequencies respectively. These frequencies can be controlled by changing the DRA dimensions. A dielectric resonator with high permittivity is used to mi...
